Description

technical field [0001] The invention belongs to the technical field of wind power generator manufacturing, and in particular relates to a manufacturing process of a hybrid excitation permanent magnet wind power generator. Background technique [0002] The structure of the hybrid excitation permanent magnet synchronous wind turbine is quite different from that of the ordinary permanent magnet wind turbine. It is mainly reflected in the fact that the former adopts a modular unit structure on the rotor and stator. The whole, and the rotor also adopts the "dovetail embedded" structure, which makes the processing accuracy of the stator and rotor punching more demanding, so the processing process is more complicated, and it is more difficult to complete the processing and assembly tasks with high quality. [0003] In addition, the processes of hybrid excitation permanent magnet synchronous wind turbine rotor core press-fitting, stator core press-fitting and motor assembly are much...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a manufacturing process of a hybrid excitation permanent magnet wind power generator, aiming to solve the problem of the complex structure of the rotor "dovetail embedded laminations" of the hybrid excitation permanent magnet synchronous wind power generator, which has many edges and corners, resulting in poor order of the laminations , which increases the difficulty of stamping, stacking, and assembly; the stator is spliced ​​by several stator core units into a full-circle stator core, which is difficult to splice and it is difficult to ensure the concentricity of the inner circle of the stator core after splicing; it has double stators and double rotors Make it more difficult to center the problem in the general assembly process
